Descartes Meditations The Wax Example
The Extension of the Cogito For even if, as I have supposed, none of the objects of imagination are real, the power of imagination is something which really exists and is part of my thinking. Lastly, it also the same ‘I’ who has sensory perceptions, or is aware of bodily things as it were through the senses. For example, I am now seeing light, hearing a noise, feeling heat. But I am asleep, so all this is false. Yet I certainly seem to see, to hear, and to be warmed. This cannot be false; what is called ‘having a sensory perception’ is strictly just this, and in this restricted sense of the term it is simply thinking [AT VII, 29].
The Wax Let us consider the things which people commonly think they understand most distinctly of all; that is, the bodies which we touch as see. I do not mean bodies in general – for general perception are apt to be somewhat confused – but one particular body. Let us take for example, this piece of wax [AT VII, 30].
Senses Smell Fragrance of flowers In short, it has everything which Taste appears necessary Sweetness to enableofa honey body to be known as distinctly as possible [AT Sound VII, 30]. Knocks when rapped Touch Hard and cold Sight White, cube, one inch cube
Change Smell No Fragrance of flowers Taste No Sweetness of honey Sound No Knocks when rapped Touch Not Hard and cold Sight Not White, Not a cube, Not one inch cube
Change But does same wax remain? It must be admitted that it does; no one denies it, no one thinks otherwise. So what was it in the wax that I understood with such distinctness [AT VII, 30]?
Imagination Let us concentrate, take away everything which does not belong to the wax, and see what is left: merely something extended, flexible and changeable [AT VII, 30 -1].
Imagination But what is meant here by ‘flexible’ and ‘changeable’? Is it what I picture in my imagination: that this piece of wax is capable of changing from a round shape to a square shape, or from a square shape to a triangular shape? Not at all; for I can grasp that the wax is capable of countless changes of this kind, yet I am unable to run through this immeasurable number of changes in my imagination, from which it follows that it is not the faculty of imagination that gives me my grasp of the wax as flexible and changeable [AT VII, 31].
Mental Scrutiny But what is this wax which is perceived by the mind alone? It is of course the same wax which I see, which I touch, which I picture in my imagination, in short the same wax which I thought it to be from the start. And yet, and here is the point, the perception I have of it, is a case not of vision or touch or imagination – nor has it even been, despite previous appearances – but of purely mental scrutiny [AT VII, 31].
